Sorry, I had a shower thought after I made my original reply...
...This is more of a "philosophical" approach and are a couple ideas I've also borrowed from my corporate life and self development books I've read over the past couple years.
Outcome Goals vs. Identity Goals - "Atomic Habits" by James Clear
This is a concept that really resonated with me when I was reading the book. For context I was starting the 75 Hard health challenge; aside from exercising, eating clean, and reading everyday- no booze - was something I knew I was going to struggle with. That's where this concept really helped. In the context of Fitness, and Outcome Goal would be something like "I want to lose 20 pounds" where an Identity Goal would be more like "I want to do/eat in a way that I will be leaner." That shift from what thing you'll be holding onto at the end of a journey; to living the journey and doing the things that someone 20 pounds lighter would do was a massive a-ha moment for me.
In the world of music, you can think about "I want to make a 10 track album by December" as an Outcome Goal. The Identity Goal is "I want to be a person who makes music enough to have an album's worth of music by December." You're shifting the emphasis from the Result to the Behaviours.
Process & Organization - "Getting Things Done" by David Allen
I've always been a fairly organized person, specifically with the use of my Bullet Journal, but that was almost entirely in a work setting. My personal life was quite the opposite and sort of a brute force approach. My days off were just doing as many chores, tasks, errands that I could but with no real rhyme or reason. This is fine if you have set recurring tasks (Monday is house keeping, bank, and groceries, Wednesdays was barber, car wash, dry cleaners) but leaves you scrambling when the unexpected and one-off tasks pop up. Again, the Bullet Journal did wonders to help me get my personal life as organized as my work life, but I took a lot from this book to further systemize my tasks, and tackle bigger projects. I may not use the systems as rigorously as outlined in the book, but the few pieces I incorporated into my existing task management has worked wonders. This book is definitely worth a read as it focuses, and provides plenty of examples of systems and Process.
Workflow is a word that's almost become taboo in the Online Music World, as there are a ton of "workflow hack" videos out there. But, I truly believe it is a key part of any process...even music. You can benefit by having some sort of system and process in place in the music world. Personally, having Maschine routed templates to Logic are a huge lifesaver. Having a defined, repeatable system to track from the MPC 100 to Logic is another "process" that has saved me time and headache. I know people have arrangement templates, and mixing presets. These are all thins that will allow you to focus more on the abstract and creative part of music rather than minute "technical" details.
Behaviours + Process = Results
This is something my old boss used to preach! It's also a mantra I took with me as I moved up the corporate ladder and even when I completely changed industries. If anyone has worked in a corporate setting, you know the term KPIs and Metrics. What my boss taught me is that you Behavioural metrics and Result metrics - not dissimilar to Outcome/Identity Goals. What makes good behaviours translate to good results is calibration...something you cannot do unless you have a Process!
The applications of this philosophy are near endless. I've also found that applying a broad concept like this to smaller, finite, tasks is incredibly helpful. Historically, I always had shit mixes. The Identity I adopted was that of "oh well, I'm just a hobbyist mixing in headphones." Obviously my Result was shit mixes. Even when I did attempt to get better mixes, I didn't have a process. I'd watch a video try it, not get the desired result, then abandon ship. However, once I committed to a mixing process, and worked it, they eventually did get better. The Behaviour or Identity of "I'm proud of my music and want to present it in that way" coupled with persistence, calibration and a process that can be understood intimately, and tweaked to fit my needs lead to better mixes!
All this to say, when in a slump (low sales for a month, put on a few pounds of fat, not making as much music) taking some time to re-align, figure out your desired Identity, it's associated Behaviours, and a trackable Process can be very beneficial to the long term journey.
